The term "hardbitten" combines "hard," from Old English "heard" (solid, severe), and "bitten," the past participle of "bite." Originally literal (e.g., a horse hardened by the bit), it evolved metaphorically to describe people toughened by adversity. The imagery suggests enduring repeated "bites" of hardship, leaving one resilient but unyielding.
